Welp, someone basically made that 'Black Mirror' dating app

The polarizingBlack Mirror Season 4 episode "Hang the DJ" depicted a futuristic dating app in which an AI called "Coach" only gives daters a set amount of time — 12 hours, or even 12 years — to date a potential partner before they must move on to their next match.

Now, of course, somebody has actually built an app inspired by the somewhat dystopian system. First spotted by Forbes, it's called Juliet and is available for free in the App Store.

On Jan. 2, a 24-year-old programmer named Julian Alexander hosted a Reddit AMA in which he debuted Juliet. The concept is that users of the app will only be paired with one prospective partner at a time, for a set amount of time. There are no profiles, and no swiping — just basic info like sexual orientation and location.

After the time in which you're allowed to talk and connect expires, users fill out a survey about the other person and how it went. The AI then supposedly learns from your experience and tries to match you with a better fit next time, and the time after that, and the time after that.

"She just does that until she finds you someone that’s really good for you," Alexander, who refers to his app as a "she," said on the phone with Mashable.

Reddit users were quick to notice the similarity between Juliet and the Black Mirror premise. The top comment on the AMA, with 5.8K upvotes, directly asks whether Alexander got the idea from "Hang the DJ." To which Alexander replied that he is a huge fan. Alexander confirmed to Mashable that the Black Mirror episode did inspire the app's creation.

"Charlie Booker, the creator of Black Mirror, is an inspiration," Alexander said. "He does a great job depicting the merge between humanity and technology. I just want Juliet to do the same thing."

Juliet is in no way linked to Black Mirror, officially — Netflix actually rolled out a spoof of the Coach app on Valentines Day last year. But likely due to the app's closeness to the episode's concept, the AMA climbed to the top of the r/AMA subreddit and became #14 on the Reddit front page. It currently has 7.8K upvotes.

"The similarity between Juliet and Black Mirror definitely helped spark interest in my Reddit AMA," Alexander said. "I was really surprised how many people loved the show and the concept of Juliet."

There's a sizable Black Mirror following on Reddit — the show's subreddit has 224K subscribers. So even if the Coach app concept in the show was all part of, ya know, a larger meta-plot about what really makes two people a "match" and the limits of AI in our quest for love, Alexander says people have been eager to try out its closest real-world equivalent.

"I’ve had to upgrade my infrastructure a few times," Alexander said. "It’s been pretty crazy to be honest."

Alexander said he has acquired "thousands" of users over the past week.

However, "thousands," to be frank, is not a ton of users for a dating app. The number of users is especially important for a burgeoning dating app, since how well they work is extremely dependent on how many potential people it can match you with. That is certainly true for Juliet, but perhaps to a somewhat lesser extent, since the whole concept is that it only matches you with one person at a time.

"A lot of other apps focus on a quantity approach." Alexander said. "I really wanted to go with a quality approach, matching the user one person at a time."

The concept itself is not entirely novel. On Bumble, users only have 24 hours to start chatting before the match expires. And other apps including Coffee Meets Bagel, Once, and The League all limit the amount of matches you're given per day — all part of a trend Business Insider and Time Out New York call "Slow Dating." An app called Ditto takes it one step further, to Juliet's level, with a one-match-at-a-time model.

And Juliet's not-quite-astronomical rise has not been entirely smooth sailing. Some app reviewers complain that they do not like the people they were matched with; that, of course, will happen, when you're matched with someone based on nothing (at least at first).

It also did not initially take location into account when making a match, so users complained that they were getting matched with people whom they would never encounter in real life. That oversight prompted negative reviews in the app store. Alexander has since rolled out a location feature on Jan. 7, and said he's getting positive feedback.

Of course, Juliet's success depends on that whole "getting smarter" thing. For an AI-dependent app, the AI has to actually ... work. Devising the perfect formula for a good date —let alone love — is something corporations and scientists are eternally struggling to get right, if it's possible to do at all.

The love clock is ticking.

Ultimately, Alexander hopes the happy ending in "Hang the DJ" will prevail over Black Mirror's underlying skepticism about technology's role in our lives.

"I hope for them to find love," Alexander said of his users. "Isn’t that what everyone’s looking for?"

And for people who still find the time limits weird, and are wary of using an app from a Black Mirror-loving developer?
